Smartphones in the Future
Smartphones are very smart,but how about their owners?Are their owners as smart as the phones in the future?We do not know.Some owners are smarter than their phones,while other owners are not as smart as their phones,or less smart than their phones.If the owners are less smart than their phones,their smartphones are a waste of money and time for their owners,since the owners do not know how to use their smartphones.If the owners want to outsmart their smartphones,they have to work hard to become smarter,which not many of them can do.So what can we expect in the future for smartphones?
DONE.

Computer networks
Now every almost have computers, and computer good does have its downside - it depends on how you use. If you want to ask me: I on the computer do what, I can tell you, I will do a lot of things in the computer. May first and have out-of-town relatives chat, then can check information, listening to music, watching movies, paint... My favorite on the computer music and watching movies, because it very relaxing my mood.But the most people used compter to surf the internet.Now Let us know about the computer network
Ⅰ.Introction
Computer networks,the wide spread sharing of information among groups of computers and their users,are a central part of the information age.The popular adoption of the personal computer(PC)
and the local area network (LAN) ring the 1980s has led to the capacity to access information on a distant database;download an application from overseas;send a message to a friend country;and share files with a colleague-all from a personal computer.
The network that allow all this to be done so easily are sophisticated and complex entities.They rely for their effectiveness on many cooperating computers.The design and deployment of the wordwide computer network can be viewed as one of the great technological wonders of recent decades. Nowadays Intemet is very popular all over the world, especially in some big cities. Do you know when the Intemet was first established? Built in 1960s, the Internet was a crude network of a few computers which shared information. If one of the computers broke down, the whole networks would be unable to work, causing continual problems. At first, just the government had access to the Internet, using it for communications among different branches. However, by 1970s the Internet had been used in universities, banks, and hospitals. At the beginning of 1990s computers became affordable for common people and this affordability increased the use of the Internet by people,It is said that each day tens of millions of people log off, making it the most important part of people's life.
Ⅱ.Local Area Network
One of the most dramatic events in computer networking has been the introction and rapid growth of local area network(LAN) as a way to standardize the system of linking computers used in office systems.As the name suggests,this is a means of connecting a number of computing elements together.At the simplest level,a LAN provides no more more than a shared medium (such as a coaxial cable to which all computers and printers are connected) along with a set of rules that govern the access to that medium.The most widely used LAN,Ethernet,used a mechanism called Carrier Sense Multiple Access-Collosion Detect(CSMA-CD).This means that each connected device can only use the cable when it has established that each connected device is using it.If there is contention, the device looking for a connection backs off and tries again later.The Ethernet transfers data at 10M bits/sec,which is fast enough to make the distance between devices insignificant.They appeat to be connected directly to their destination.
There are many different layouts(such as bus ,star,ring,see Figure 6A-2)and a number of different access protocols for LANs.Despire this variety,all LANs share the feature that they are limited in range (typically they cover one building) and are fast enough to make the connecting network invisible to the devices that use it.
In addition to providing shared access,modern LANs can also give users a wide range of sophisticated facilities.Managenment software packages are available to control the way in which devices are configured on the local area network (LAN),how users are administered,and how network resources are controlled.A widely adopted structure o local network is to have a number of servers that are available to a (usuallu much greater) nember of clients.The former,usually powerful computers,provide service such as print control,file sharing,and mail to the latter,which are usually personal computers.
Ⅲ.Routers and brideges
The facilities on most local area network (LAN) are very powerful.Most organizatonns do not wish to have small isolated islands of computing facilities.They usually want to extend facilities over a wider area so that groups can wok wtthout having to be located.Routers and bridges arespecialized devices that allow two or more local area network (LAN) to be connected.The bridges is the more basic device and can only connect local area network (LAN) of the same type.The router is a more intelligent component that can interconnent many different types of computer network.
Many large companies have corporate adta network that are founded on a collection of local area network (LAN) and routers.From the user’s point of view,this arrangement provides them with a physically diverse network that looks like one coherent resource.
Ⅳ.Wide Area Networks
At some point,it becomes impractical to extend a local area network (LAN) any further.Physical limitation sometimes drives this,but more often than not there are more concenient or cheaper ways to extend a computer network.Two major components in most real computer networks are the public telephone and data networks.These provide long-distance links that extend a local area network (LAN) into a wide area network (WAN).Nearly all of the national network operators offer services for the interconnection of computer networks.These services range from simple, low speed data links that work over the public telephone network to sophisticaied high speed data services that are ideally suited to the interconnection of LANs.These high speed data services are usually referred to as broadband connection.It is anticiopated that they will provide the necessary links between LANs that make what is called the information superhighway a reality.
⑸ 寻求一有关计算机方面的介绍的英语作文
We build computer to solve problems.Early computer solved mathematical and engineering problems，and later computers emphasized information processing for business applications.T-
oday，computers also control machines as diverse as automobile engines，robots，and microwave ovens. A computer system solves a problem from any of these domains by accepting input，processing it，and procing output. Fig. 1-1 illustrates the function of a computer system.
Computer systems consist of hardware and software. Hardware is the physical part of the system. Once designed，hardware is difficult and expensive to change. Software is the set of programs that instruct the hardware and is easier to modify than hardware. Computers are valuable because they are general-purpose machines that can solve many different kinds of problems，as opposed to special-purpose machines that can each solve only one kind of problem. Different problems can be solved with the same hardware by supplying the system with a different set of instructions.that is，with different software.

计算机组成原理
计算机硬件
人们为解决问题而制造计算机。早期的计算机解决的是数学和工程问题，后来计算机着重解决商业应用中的信息处理问题。如今，计算机还用来控制如汽车发动机、机器人和微波炉等各式各样的机器。计算机系统解决上述这些领域中的任何一个问题都是通过接收输入、处理问题和生成输出来实现的。图1-1说明了计算机系统的功能。
计算机系统由硬件和软件组成。硬件是系统的物理部分。硬件一旦设计完毕，要修改是困难的，并且花费也大。软件是指挥硬件的程序集合，比硬件容易修改。计算机之所以有用，是因为它们能解决很多不同类型的问题，是通用的机器。相对而言，每种专用机只能解决一类问题。通过为系统配备不同的指令系统，也就是配备不同的软件，能用同一硬件去解决不同的问题。
⑹ 简述按覆盖范围划分计算机网络的分类类型有哪些 英语缩写分别是什么
按覆盖范围划分计算机网络可分为三类：局域网、城域网和广域网。
它们的相应英文缩写是：LAN、MAN和WAN。
计算机网络是指将地理位置不同的具有独立功能的多台计算机及其外部设备，通过通信线路连接起来，在网络操作系统，网络管理软件及网络通信协议的管理和协调下，实现资源共享和信息传递的计算机系统。
(6)计算机网络分类英语作文扩展阅读：
从整体上来说计算机网络就是把分布在不同地理区域的计算机与专门的外部设备用通信线路互联成一个规模大、功能强的系统，从而使众多的计算机可以方便地互相传递信息，共享硬件、软件、数据信息等资源。简单来说，计算机网络就是由通信线路互相连接的许多自主工作的计算机构成的集合体。
计算机网络就是由大量独立的、但相互连接起来的计算机来共同完成计算机任务；最简单的计算机网络就只有两台计算机和连接它们的一条链路，即两个节点和一条链路。

我们都忙于使用使用因特网,但是我们中有多少人知道因特网的历史呢? 当因特网在60年代建立时,许多人感到非常惊讶.在那时,计算机是非常大和昂贵的.计算机网络运行的也不是很好,如果网络中的一台计算机不能工作了,那么整个网络就停止工作了.所以一个好的网络系统必须建立,他应该被不同的计算机充分使用.如果网络中的某一部分不能工作了,但是信息能被通过另一部分传送,电脑网络系统将不停地一直这样工作. 起初,因特网仅仅被政府部门使用,但是在70年代初,大学、医院和银行也获准使用.但是计算机依旧非常昂贵,并且网络难于使用.到了90年代初期,计算机变得比较便宜,并且比较容易使用.科学家发明了软件,使得网络运用更加方便. 今天上网非常容易,据说有每天有百万的人使用因特网,发送邮件在学生间越来越受欢迎. 现在因特网已经变成人们生活的非常重要的一部分.
